Cancel subscription and Refund
I accidentally payed for subscription for an app. And now I want to refund. I removed my card details even accidentally. What can I do. Need support immediately.
See these two links:

Note: Apple's policy is all sales final, so they may or may not refund you, but you'll have to take that up with them directly. This is a user to user only forum.
